NassboardsWaterproof Tanking Tape - Aqua Elastic Self Adhesive Butyl Joining Permanent Strong Sealing Tape for Waterproofing Bathrooms, Shower Wet Rooms, Use Outdoors Indoors Preventing Leaks (20m)

This was great, it's very sticky so it takes a bit of time to get used to but once you do it's so good!!!Great quality too! Easy to use very quickly

Excellent item and very sticky. Recommended

This stuff is REALLY sticky! Applies well to single flat surfaces but two sides of a corner can be tricky if (like me) you’re using it for the first time.I’ve used it as a precaution in case of any unlikely leaks under the siliconed shower board walls - I’m hoping it never has to be put into use as a water barrier!

Easy to use and it sticks to anything

I had a triple inset shower valve malfunction dripping water through my cavity so had to hack through the bathroom wall to get at it. I then had to secure new backing board and re-tile. I found this worked well on the backing board. There is a definite knack of removing the greaseproof backing the way you might a put a plaster on, peel the backing paper off as you work along dabbing it and to smooth the sticky side on the wall.

Really good for what it is.

Saved me so much time when waterproofing my wetroom. Rather than using tanking slurry and membrane tape, which would have been messy and time consuming, I was able to tape up within 1 hour. I did one line using traditional methods and quickly gave up!! Done and dusted no mess at all. Customer service was great had an issue with one of the tape as the backing paper was too sticky and would not tear off resulting in me wasting alot of tape. I reached out and a new 5m free of charge was posted out on a next day delivery. Best practice, I used OB1 around all the edges of the wetroom. Once dry after 24 hours I used the tanking tape. After tiling I used silicone. Overall ID BE shocked if any water passed through!

This is not Nassboards tape, it is generic (unbranded) tape, which could be bought elsewhere for 1/4 of the price. The tape is good and quick delivery is appreciated, but it should not be labelled as a branded product (with the premium it brings).
